" To all whom t may concern:

Be it known that I, MYER M. Manns, a citizenA of the United States, residing at Chicago, in the county of Cook and State i to the inside of the shade; but in the earlier construction the vertically movable element co-operates with stationary elements located on the Vopposite sides of the holder and adaptedto engage the shade from the outside thereof. Specifically, the stationary supporting elelinents are in the form of pins which project radially inward from the holder and enter an annular channel formed inthe upper rim of the shade. The result is that in that specitic form the operator mustsee that the shade is held in engagement with the pins while the movable support is being `slid downward to acting posif tion. If during manipulation the shade leaves the' pins it willdrop. my invention is to provide means which will An object of hold the' Y shade in engagement with the holder on one side while the movable supporting elementJ on the opposit-e side is being adjusted. This I accomplish, generally speaking, by substituting for the pins of ,the previous construction a supporting element capable of passing to the inside of the shade and confining the shadevrim between `it and the rim of the shade holder.

In the previous construction also it was necessary, in order for the pins to function, to employ ashade whose upper rim was provided with a channel into which the pins might enter. One of the objects of my presyent invention is to provide a shade holder which may support shades having upper rims variously coniigurated and designed with or without annular channels. Another object is` to provide a support which will steady the shade while being adjusted and reduce any tendency for it to rock upon its support.

As to previous construction, even where the shade had a channeled upper rim, the operation was not always reliable due to the fact that both shades and shade holders have some irregularities due to exigeneies of inanufacture, and as the fixed pins were necessarily short the shade was not always properly supported. lVith my new construction, in which both shade'supporting elements pass to a considerable distance to the inside of the shade, the old diiiculties are avoided.

I accomplish my objects by the mechanism illustrated in the accompanying` drawings, in which- Figure l is a vertical central section of my device showing it applied to a shade.

Figure 2 is a side elevation of the parts shown in Figure 1.

Figure 3 is a bottom plan view on a reduced scale showing the parts illustrated in Figure 1, and

Figure l: is a sectional detail showing my device applied to a shade having a di fl'crent form of rim.

Like numerals denote like parts throughout the several views.

According to the illustrated design the body 1 of the shade holder is in the form of a canopy having slightly concave sides terminating at the bottom in a vertical flange 2.

Located at opposite sides of the body are vertically extending slots t for accomodating the Shanks of headed pins G and 7 which are secured at the inner ends to the Shanks 8 of shade supporting elements 12. These support the shade 10 and are extended circumferentially for steadying the shade when it rests upon them.

One of the pins, in this case the pin 6, is extended upward so that it may be grasped by the operator for sliding the support up 'and down. lVhile not essential it is desirable to form a hump or boss 1st in the body of the holder adjacent to the guide slots Ll. for offering a slight resistance to the downward movement of pin 6 when starting from ythe raised position. The purpose is to pre- `in the shank of the support may engage to- ;finally. limitithe downward vmovement of the support. However, .this 'function .may be performed 'byfthe lower pin 7 strikingrthe owerendofthe slot 34.

In Figure l I have shown a shadehaving the Commoniformiin which vthere is anan- =nulari channel 20.in.the.-.upper rim. =Myf'deu-vice, however, willoperateupon `shades in -whiohithefupper rimhas other forms. In fFigureff4, ;^for .eXample,` the. shade; has; an: upper. rim; 22 awhich'. is @approximately .straight whenviewed in cross-section.

lnoperationa the` operator may proceed in either .of Itwo zways, depending partlyfupon -thefformof shade .tof be used. VIffthe channeled Zrim form, as. shown; in Figures il and .2, is Ito 'fbeemployed he will {irstzbring both "of thesupports .121110 retracted-position as indicated in full lines atathe right :side of-iFigure l. @Thiswillxenablehim to insertthe rimz-between the flange 2 and'the .'movable supports. .He .will thenilowerthe supports to the position shownl-.infulllines at thegleftofxFigure Land in V:dotted lines .totherightof'Figure l. ln descending, the supports pass to the inside of the shade :and when they -lare lowered lthey securely `hold it impositionk inthe holder. As pointed out in my prior application, if the device .is mounted in a' building vwheref there is considerable vibration no harm will be done because .Lthe avibration, assisted vby gravity,

will have fa tendency tolowersthe-supports,

-which :simply serve; to ,maintain them' in acting position. .Thusthere is nodangerof the shades shaking loose.

If ashade whose: upper rimisfformed as shown,y in: Figure l4 isy to. be used the operator mayvlower one of the. supports12.vbeforefhe -adjuststhe lshade Vto1the holder. @Then all he has` to do isY tol lowers the support, on; the oppositefside. Consequently .with such; type of .shadethel support on Vone@ side maybe lowered before the shadeis'broughtl-to position, f thus requiring `the;manipulation of .lowering-'only onefsupport after the'shade has-beenpositioned. Under certain conditions, especially ifthe operatoris `placing ashade above his; head, it is not-.always-con- .venient or vpossible for both ofzthe .supports ,to be lowered vat the same/time, `but with-my device as soon as one of the supports has been lowered it will retain its side of the shade between it and the iiange 2 of the holder as illustrated at the left of Figure 4. This reduces, if it does not actually prevent, the dangerYof-the shade slipping outwhile the support on the. opposite side .isbeing lowered.

This is an improvement overmypriortype for with it the operator must see to it that the shade is held in engagement with the supporting pins while the movable element is being lowered into .Y engagement.

Having thus described my invention, what l claim asnew `and desireto ysecu-re` by :Letters Patent. is p l. A .shade :holder flaring outward and downward. iii-.general .and having a, .depend- .ing flange at thelowerfrim,xthe` shade holderl .having slots. .arranged t in yvertical planesl in the flaring portion, .and independently mov- 'able shade supports 1 having handles projecing 4out through the-slots, said shade-supports being slidably. mounted upon. the; inner; flar- .ing surface and passing .obliquely downward and outward a slight distance Jbelo'w the lower edgeofthefiiange for retainingzthe shade rim withinsaid iange .andi-for passing .to Aa-point under the Ishade rim, :said Ashade -supports having. circumferential l extensions for steadying the shade. v
